My first thought was, "Well, not right now". Next was, "Well, I don't exactly want a general tutorial. I just want someone/something to answer my specific questions when I'm working on something and run into problems." And finally, "What I really want is a step-by-step series of lessons with specific assignments, walking me through writing a song in a DAW (using mine, which is Reaper) and doing everything the way I want to do things." Not too demanding, am I???
Maybe what I really want is a class (online or live) in which the participants are given assignments, one after another, until they end up with a song. Guided songwriting. Using Reaper, of course, so I can learn how to use it better.
